had Biden flexed his muscle and threatened Putin to take him out in the school yard...there wouldn't have been an invasion of Ukraine.
the real problem here is, since no one deterred Russia from invading Ukraine it will ultimately lead to the disassembly of Ukrainian government and it's sovereignty or lead to a WW3...which nuclear weapon is at the play button!
Putin is a bully. Ukraine broke away from the USSR in 1991. Putin lives in his mind that he can reunite the original USSR countries. He’s afraid of NATO influences in the East, he’s afraid his alliances will be outnumber. Therefore he wants to take back Ukraine by force.
